A simple and low-cost control strategy for active power filters implemented with pulsewidth modulation voltagesource inverters (PWM–VSI’s) connected in cascade is presented and analyzed in this paper. The principal component of the control circuit is an INTEL 8031 AH microcontroller, which generates the current reference waveforms and respective switching patterns for each inverter. The switchi...

The problem of controlling single-phase shunt active power filters is addressed in presence of nonlinear loads. The control objective is twofold: (i) compensation of harmonic and reactive currents absorbed by the nonlinear load, this objective is referred to as power factor correction (PFC); (ii) regulation of the inverter output capacitor voltage. A two-loop cascade control strategy is develop...

The problem of controlling single-phase shunt active power filter is addressed in presence of nonlinear loads. The control objective is twofold: (i) compensation of harmonic and reactive currents absorbed by the nonlinear load; (ii) regulation of the inverter output capacitor voltage. A two-loop cascade control strategy is developed that includes an inner-loop designed, using the backstepping t...

Abstract— This paper presents the simulation of three phase five-level modular multilevel cascade inverter based on double-star chopper-cell (DSCC). The multicarrier PWM techniques such as Phase disposition PWM (PDPWM), Phase opposition disposition PWM (PODPWM), Alternate phase opposition disposition PWM (APODPWM), and Phase shift PWM (PSPWM) is employed and a comparative study is done based on...

-The inspiration for the use of the resonant inverter shoots from an aspiration to minimise the switching losses in the inverter devices. This paper portrays an exhaustive study on losses in the resonant DC link inverter. Equations for accessing the diverse losses in the resonant DC link inverter and a corresponding hard switching inverter are developed. Based on these equations, a design optim...
